Abstract

<p> </p> <p><strong>Objective:</strong> Some people are slower to respond during lifestyle interventions. An adaptive “rescue” intervention may improve outcomes among slow responders. The impact of a worksite “rescue” intervention for early slow responders was evaluated.</p> <p><strong>Research Design and Methods:</strong> Employees ≥ 21 years old with prediabetes were stratified to intervention using a 2.5% weight loss (%WL) threshold at week 5. Outcomes were assessed at baseline and 4-months using mixed effect and linear regression models.</p> <p><strong>Results:</strong> Significant improvement occurred in mean %WL, glycemia, total cholesterol, and triglycerides in the standard compared to adaptive (GLB+) intervention (all P ≤ 0.01). However, GLB+ also experienced significant reduction in %WL and glycemia (all P < 0.01). %WL at week 5 significantly predicted %WL at 4-months (P < 0.0001). Between-group difference of 4-month %WL was not significant for someone achieving 2.5%WL at week 5.</p> <p><strong>Conclusions:</strong> Diabetes prevention programs should consider weight loss success following one month of treatment and offer a “rescue” intervention to early slow weight loss responders. </p>
